New CXRacing Twin Turbo System Psichotic Stroker Install

18. All hooked up and ready for action, the twin-turbo, carbureted 347 produced 919 hp and nearly 750 lb-ft of torque before we called it quits. The use of tight A/R turbine housings produced a rising boost curve that was climbing at a rate of 1 psi per 100 rpm at the top of the rev range. The result was a power gain of 45 hp per 100 hp, meaning there was a ton more power left in the combo had we elected to rev the motor higher.
